SILO.

Specification of Letters Patent.

Application filed January 20, 1912.y Serial N o. 672,413.

To all whom 'it may concern.'

Be it known thatI, HENRY DrEEL, citizen of the United States, residing at Long Prairie, in the county of Todd and State of Minnesota., have invented certain new and useful Improvements in Silos, of which the following is a specification.

This invention relates to building constructions, and particularly to the construction of silos.

The primary object of my invent-ion is t e provision of a silo so constructed as to pr vent the ensilage from freezing in cold weather. l y

A further object is the provision in this connection of a double Wall silo, the space between the walls providing a warm air space adapted to be connected to some source ofpwarm air. I

Another object is the formation of ,Warm

air ducts extending Within the Walls of the silo from inlet openings located in the Ibasement of the structure to out-let openings disposed in the upper portion of the structure and opening to the outer air.

A further object is to improve the general construction of silos by the use of concrete blocks of peculiar form bonded together by tie bolts, these concrete blocks being so arranged that after the tie bolts are in'place, and the inner aud outer blocks separated by division or spacing members, as will be later fully described, the tie bolts may be tightened to draw thel outer vand linner Walls formed by the blocks into bonded relation to each other. A

Other objects will 'appear in the course of the following description. l

In the drawings: Figure 1 is a vertical sectional viewofmy improved silo upon the line 1 1 of Fig. 3; Fig. 2 is a horizontal view on the line 2 2 of Fig. l; Fig. 3 is a horizontal section on the line 3 3 of Fig. 1; Fig. 4 is another face view of one half of the outer wall of the silo, the inner wall being removed; Fig. 5 is, a vertical detail section of the upper end of the wall and the adjacent roof beams; Fig. 6 is a detail horizontal section through a corner of the silo wall; Figs. 7 and 8 are perspective views of the outer and inner Wall blocks` respectively; and Fig. 9 isa perspective view of one of the members of which the horizontal division pieces 17 are composed.

Corresponding and like parts are designated by the same characters of reference throughout the several views.

I have illustrated my improved silo as being oct-angular in form, but, of course, do not Wish to be limited to any particular shape for the silo, as it might be round, square, vor of anyother desired figure. The base 2 of the silo has, of course, the same form in plan as the walls of the structure. This base is preferably solid and made of concrete,-v brick, stone or other suitable material. The Hoor 3 of the base is preferably of concrete. The upper face of the base Wall is formed with a duct or passage 4, preferably opening along its entire extent upon the upper face of the wall, which duct extends nearly around the lbase wall. A Warm air inlet opening or passage 5 extends from the exterior of th'e building into one end of this duct and a like inlet passage or opening 6 also extends from the exterior of the .building into the other end of the duct.

Thewalls of the silo which extend above the ground line are formed of an inner wall 7 and an outer wall 8 separated from each other to provide a space 9 which registers with the space 4 of the base. iVhile I do not wish to be limited, broadly speaking, to any particular material for the outer and inner walls of the silo or any particular construction of these walls, they are preferably formed according to my invent-ion of blocks of artificial stone, as will be later described.

The roof 10 is of any ordinary and usual construction, and formed and provided with the usual ventilalting louver 11 and chute 12.

The interspace 4 of the upper face of the base, and the interspace 9 between the outer and inner Walls of the superstructure is divided into two main portions by a vertically disposed division wall 13 preferably composed of a joist or scamtling located between the outer and inner blocks of which the side Walls of the silo are composed, and extending from the bottom of the space 4 to the junction of the walls with the roof. This division Wall 13 is located preferably diametrically opposite to a pointbetween the two openings or passages 5 and 6, or, in other Words, diametrically opposite to u per and lower door openings 14 and 15, W ich are framed by the door casing 16. Vertically disposed division members 16EL extend Patented Apr. -15, 1913.-

above and below the door casings so as, in conjunction with a division member 13, to divide the space 9 into two lateral sections.

Extending horizontally within the space between the two walls are a series of division members 17, each member being composed of a. plurality of sections or pieces 17a and each member as a whole being of less length than the distance from one inlet opening 5 or 6 to the vertical division wall 13, as shown in Fig. 4. These division members are set in staggered relation to each other, that is, one of said members 17 at one end abuts against the division wall 13,

' but is spaced from the vertical division wall 16 or' the casing 16, while the next adjacent members aboveand below abut against the wall 16a or the casing 16, but not against the division wall 13. These members, therefore, alternately abut against the division wall 13 and the casing 16 or division wall 16?. There is thus provided, as shown by the projection, Fig. 6, on each side of the building, and extending half-way around it, a continuous passage or tine 18 which extends in a zig-zag direction from the warm air entrance opening in the base to the roof, where it opens to the outer air, as by an outlet 6. It will thus be seen that there are practically two sets of grooves or warm ir passages, each extending substantially ralf-way around the building, so that the inner wall of the silo as a whole is inclosed Vformed of a sma by a warm air space. This warm air space may be connected to any source of warm air, but preferably it is connected to vent-ilat-ing openings extending trom a stable or cow house. AI have found in practice that by connecting the silo interspace by a ue leading to and Ventilating the cow house or stable, that the warm air so conducted to the silo will entirely prevent the ensilage from freezing, and that at the same time a erfect ventilation of the stable or cow iiouse is provided, inasmuch as acontinuous iiue is formed surrounding the silo and extending upward and discharging at its uper end to the outer air. 1t is extremely icult in cold countries to prevent ensilage from freezing within the silo, but by my invention it is ossible to secure this object with no'expen iture of money except that incident to'buildin the silo.

Because the silo 1s shown as octagonal or polygonal in plan, the division members can not be formed each in a Vcontinuous strip, but'l must be formed. preferably of strips each owvhich is equal in lengthto one of the sides of the polygon. As illustrated in Fig-9, each strip 17"-, which is preferably l joist or scantling, is beveled at its ends so that when the strips are placed together, as illustrated in Fig. 6,

' the end of one strip will butt against the endof the next succeeding strip. As illustrated, one end of a strip butts against one end of the adjacent strip, while the other end of the first-named stri overlies the abutting lend o' the next adjacent strip or piece.

In building the silo, the inner wall is first built up to a certain height from the ground and then the irst division members 17 are nailed or otherwise attached to the inner wall. The outer wall is then built up to the height of this member 17, and` then the inner wall continued upward until the next member 17 is put in place, and'so on. The uppermost member 17 is nailed or otherwise attached not only to the inner wall, but to a cap beam 20 which rests upon the outer wall, as shown in Fig. 5, and upon which, in turn, the roof beams 21 and 22 are supported.

As previously stated, the outer and inner walls of that portion of the silo which extends above the ground, are preferably formed of blocks of artificial stone. cement or other suitable material.` The block for the inner wall is illust-rated in Fig. 8, and 011e for the outer wall is shown in Fig. 7. The blocks 23 for the inner wall are thinner than the blocks 24 for the outer wall, but both inner and outer wall blocks are formed with marginal grooves or channels, as 25. The grooves or channels may either be left empty or filled with cement or other bonding material 26, thus closing joint between abutting blocks andl preventing the passage of moisture or of air through between the abutting blocks. rllhese grooves or channels 25 also form seats for tie bolts 26. Preferably, the edges of the blocks are transversely grooved, as at 27, so as to inclose and fit over these stay or tie bolts.

As previously described, the longitudinal dividing members 17 composed of the strip 17 a are put in place as the wall is built up. Hence, each course of blocks 23 and 24 may be tied to each other as the work progresses, without danger of the blocks forming the walls being drawn toward each other, the members acting as spacing members, while the bolts 26 tie the walls to 'each other and into close contact with the spacin members or division members 17. After t e bolts 26 of a course have been put in place within the notches or grooves 27, the grooves 25 may be filled with cement, as before described, and the next course of blocks put in position. 1t is not, however, absolutely necessary to use cement, as if cement is not used the panels 25 will form a space which will suicientl insulate the joint between the blocks. f course, at the corners the blocks 23 and 2a will be angular in form, as illustrated in F ig. 6 these corner blocks being designated 23a and 24a. After the wall has been built up with the strips 171 in place, spikes may be driven from the inside face of the inner Wall through the strips 1'?a and into or through the outer wall. Preferably, the wall of the silo is relatively thin, and l have found in practice that with the outer blocks four inches in thickness and the inner blocks two inches in thickness, and the outer and inner blocks spaced apart two inches, the wall is amply strong and atl the same time thoroughly protective of the ensilage.

It will be seen that my method of constructin f silos provides asilo which is thoroughly ry, weather proof, and which will prevent the eifsilage from freezing and at the same time provide a duct whereby warm air together with foul odors from the cow house or stable may be conducted away.

My improved silo may be readily built at relatively small cost, and it is obvious that.

while preferably this silo is built of cement or concrete, brick or other like material may be used on the exterior, and lathes, plaste or other desired finish on the interior, an

that I need not, therefore, be limited to the precise construction of the silo described in order to secure the general advantage claimed in my invention.

Having thus described the invention, what is claimed as new is:
